Technical Field
[0001] The present invention relates to the technical field of voltage transformers, and particularly to a voltage transformer with a fast heat dissipation function. Background Art
[0002] As a key measuring device in the power system, the long-term operation stability of the voltage transformer directly affects the monitoring accuracy of the power grid. With the advancement of the construction of the smart grid, the problem of temperature rise of traditional voltage transformers under high-load conditions has become increasingly prominent.
[0003] A heat dissipation type voltage transformer (Patent No.: CN201711387585.7) is disclosed in the prior art. It dissipates heat through a fan, cannot achieve fast heat dissipation, and the use environment is limited and cannot be used in complex environments such as outdoors. Therefore, the existing voltage transformers mainly have the following problems: (1) cannot achieve fast heat dissipation; (2) the local temperature of the transformer is too high, and the transformer cannot be evenly cooled. Summary of the Invention
[0004] The purpose of the present invention is to provide a voltage transformer with a fast heat dissipation function to solve the problems proposed in the prior art.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A voltage transformer with a fast heat dissipation function includes an insulating housing. Inside the insulating housing, there is a transformer body. Outside the transformer body, there is an isolation cover. Above the isolation cover, there is a cooling plate. Inside the cooling plate, there is a refrigeration plate. The cooling plate is sequentially connected to an output pipe, an intermediate pipe, and an input pipe. The intermediate pipe is connected to a scroll tube. Below the isolation cover, there is a collection plate. Inside the collection plate, there is a temperature measuring plate. At the four corners of the insulating housing, there are shock-absorbing springs.
[0006] The insulating housing is provided with a liquid injection port, an air inlet, and a liquid discharge port. The air inlet and the liquid discharge port are located on both sides of the liquid injection port. On one side of the transformer body, there is a storage tank. The storage tank is installed on the insulating housing. The inlet of the storage tank is connected to the liquid injection port through a pipeline. The outlet of the storage tank is connected to the input pipe through a pipeline. The storage tank is filled with a coolant. The input pipe is connected in series with a delivery pump. The delivery pump transports the coolant in the storage tank into the input pipe, so that the coolant flows at a high speed in the input pipe. The storage tank stores and buffers the coolant to avoid excessive impact of the coolant and affect the normal operation of the transformer body.
[0007] The input pipe, the intermediate pipe, the output pipe and the vortex pipe are all arranged on the insulating housing. The diameter of the intermediate pipe is smaller than that of the input pipe and the output pipe. An electromagnetic valve and a flow meter are installed in the output pipe, and the electromagnetic valve and the flow meter in the output pipe are electrically connected to the control system. The vortex pipe is connected to the air inlet through a pipeline. The vortex pipe is distributed in a planar thread. A plurality of filter plates are sequentially rotatably arranged on the inner wall of the vortex pipe through torsion springs. Filter meshes are arranged on the plurality of filter plates, and the diameters of the plurality of filter meshes gradually become smaller in sequence;
[0008] When the vortex pipe performs dust removal work, air and dust are inhaled from one end of the vortex pipe. After passing through the vortex pipe and a plurality of filter meshes for dust removal, the air is discharged from the other end of the vortex pipe and collides with the coolant at a high speed to form water mist, so as to quickly dissipate heat from the transformer body through the aerosol;
[0009] When the vortex pipe is cleaned, the coolant is transported into the input pipe through the coolant transport system and the transport pump. The control system simultaneously closes the electromagnetic valve in the output pipe. The coolant enters the storage tank through the liquid injection port. The transport pump works intermittently to extract the coolant in the storage tank into the input pipe, so that the coolant enters the input pipe intermittently, forming an impact of the coolant, so as to clean the filter mesh through the intermittent coolant;
[0010] The intermittently moving coolant enters the vortex pipe through the input pipe and the intermediate pipe. Since a large amount of dust is deposited on the filter mesh, the resistance of the coolant passing through the filter mesh is relatively large. The coolant will push the filter plate and the filter mesh to flip a certain angle. While the filter plate flips, the torsion spring is compressed. The filter plate flips a certain angle and impacts on the vortex pipe; afterwards, the dust on the filter mesh becomes less after being washed by the coolant, and the resistance of the coolant passing through the filter mesh becomes smaller. At this time, the torsion spring is released, and the torsion spring pushes the filter plate and the filter mesh to flip reversely by a certain angle, and reversely pushes the filter plate to impact on the vortex pipe again. Through the intermittent movement of the coolant, multiple impacts of the filter plate are realized, and the dust on the filter mesh is impacted and dropped. After the coolant washes the plurality of filter meshes at the same time, the washed coolant is discharged from the vortex pipe into the air inlet and discharged from the air inlet of the voltage transformer, realizing the cleaning treatment of the plurality of filter meshes.
[0011] The cooling plate and the collection plate are both installed on the insulating housing. Multiple groups of cooling channels and multiple groups of collection channels are respectively arranged inside the cooling plate and the collection plate. Multiple groups of spraying ports and multiple groups of collection ports are respectively arranged on the opposite sides of the cooling plate and the collection plate. The multiple groups of spraying ports and collection ports are directly opposite to the transformer body. One ends of the multiple groups of cooling channels are all connected to the output pipe, and the other ends of the multiple groups of cooling channels are respectively connected to the multiple groups of spraying ports. One ends of the multiple groups of collection channels are all connected to the multiple groups of collection ports, and the other ends of the multiple groups of collection channels are connected to the drain port through a pipeline. The injection port and the drain port are both connected to the coolant delivery system. Flow control valves and flow meters are installed in each of the multiple groups of cooling channels, and the flow control valves and flow meters in the cooling channels are both electrically connected to the control system;
[0012] Multiple groups of refrigeration plates are provided, and the multiple groups of refrigeration plates are sequentially arranged in the cooling channels.
[0013] A collection cylinder is arranged on the upper side of the collection plate. The collection cylinder is closely attached to the inner wall of the insulating housing. Multiple groups of temperature measuring plates are provided, and the multiple groups of temperature measuring plates are sequentially arranged in the multiple groups of collection channels.
[0014] The multiple groups of spraying ports and the multiple groups of collection ports are directly opposite. The control system adjusts the opening degree of the flow control valves in the multiple groups of cooling channels according to the temperature data detected by the multiple groups of temperature measuring plates.
[0015] Multiple groups of displacement sensors are arranged on the insulating housing. The displacement sensors are used to detect the displacement of the insulating housing. Spiral grooves are arranged at the four corners of the insulating housing. Lifting shafts are threadedly connected in the spiral grooves. The lifting shafts and the spiral grooves form a threaded seal. The upper ends of the lifting shafts penetrate through the insulating housing and are provided with handwheels. Scales are arranged on the handwheels. The lower ends of the lifting shafts are connected to shock-absorbing springs. The shock-absorbing springs are located in the spiral grooves. A contact plate is rotatably arranged at the lower ends of the shock-absorbing springs. A telescopic shaft is connected between the contact plate and the lifting shaft. The telescopic shaft is a telescopic structure. The contact plate is in contact with the ground.
[0016] The vibration damping effect of the voltage transformer is a adjustable design to face different usage scenarios. The staff rotates the handwheel to the set scale. The handwheel drives the lifting shaft to rotate. The lifting shaft drives the shock-absorbing spring to rotate. While the shock-absorbing spring rotates, it moves downward in the spiral groove. At this time, the number of turns of the shock-absorbing spring between the bottom of the insulating housing and the contact plate becomes more, and the shock damping effect becomes stronger.
[0017] Connection plates and two semiconductors are arranged on both the temperature measuring plates and the refrigeration plates. The connection plates are made of metal. The materials of the two semiconductors are different. One ends of the two semiconductors are both connected to the connection plates. The two semiconductors are electrically connected to the control system through wires;
[0018] The connecting plate and the two semiconductors on the temperature measuring plate are the hot ends of the Seebeck effect, and the connecting plate and the two semiconductors on the refrigeration plate are the refrigeration ends of the Peltier effect.
[0019] The isolation cover is made of heat-conducting material, and the isolation cover conducts the heat of the transformer body outward to facilitate the rapid heat dissipation of the transformer body.
[0020] A window is provided on the insulating housing, and the window is made of a transparent material.
[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0022] 1. By increasing the cooling area with aerosol coolant to achieve rapid cooling. Air is successively sucked into the middle tube through the vortex tube. After being sucked through the middle tube, the air collides with the high-speed coolant to form an aerosol, and then is transported to the cooling channel through the output tube; the control system cools the aerosol coolant in the cooling channel through the refrigeration end, so that the aerosol coolant is cooled to the set temperature. The cooled aerosol coolant is sprayed on the isolation cover from multiple spraying ports. The aerosol coolant increases the contact area with the isolation cover, improves the cooling effect, and enables the transformer body to dissipate heat quickly.
[0023] 2. Detect the coolant temperature at different positions of the transformer body, and then adjust the coolant flow rate to avoid local overheating of the transformer body. When the control system obtains the temperatures of the coolant in multiple collection channels, the control system adjusts the opening degree of the flow control valve in the cooling channel according to the temperatures of the coolant in the multiple collection channels; when the temperature in the collection channel is higher than the set temperature, the control system increases the opening degree of the flow control valve in the cooling channel directly above the collection channel, so that the coolant flow rate in the cooling channel directly above the collection channel becomes larger, so as to uniformly cool the isolation cover and the transformer body, avoid the problem of local overheating of the isolation cover and the transformer body, and achieve targeted cooling of the isolation cover and the transformer body to improve the cooling effect; afterwards, the control system processes the current generated by the Seebeck effect through voltage transformation and rectification, etc., and uses it for the cooling of the refrigeration plate, so that while realizing detection, the energy consumption of the voltage transformer can be reduced.
[0024] 3. The filter screen is cleaned to ensure its filtering effect. The intermittently moving coolant enters the scroll tube through the input pipe and the intermediate pipe. Since a large amount of dust is deposited on the filter screen, the resistance of the coolant passing through the filter screen is relatively large. The coolant will push the filter plate and the filter screen to flip by a certain angle. While the filter plate flips, it compresses the torsion spring. When the filter plate flips by a certain angle, it impacts on the scroll tube. After that, the dust on the filter screen is washed away by the coolant and becomes less, and the resistance of the coolant passing through the filter screen becomes smaller. At this time, the torsion spring is released, and the torsion spring pushes the filter plate and the filter screen to flip reversely by a certain angle, and reversely pushes the filter plate to impact on the scroll tube again. Through the intermittent movement of the coolant, the filter plate is impacted multiple times, and the dust on the filter screen is knocked off. After the coolant washes multiple groups of filter screens at the same time, the washed coolant is discharged from the scroll tube into the air inlet and then discharged from the air inlet of the voltage transformer, realizing the cleaning of multiple groups of filter screens.

Detailed implementation manners
[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] Embodiment: As Figures 1-9 shown, the present invention provides a technical solution for a voltage transformer with a fast heat dissipation function, including an insulating housing 11. Inside the insulating housing 11, a transformer body 12 is provided. Outside the transformer body 12, an isolation cover 13 is provided. The isolation cover 13 is made of a heat-conducting material, and the isolation cover 13 conducts the heat of the transformer body 12 outward to facilitate the fast heat dissipation of the transformer body 12. Above the isolation cover 13, a cooling plate 2 is installed. Inside the cooling plate 2, a refrigeration plate 201 is installed. The cooling plate 2 is successively connected with an output pipe 21, an intermediate pipe 22, and an input pipe 23. The intermediate pipe 22 is connected with a scroll tube 24. Below the isolation cover 13, a collection plate 3 is installed. Inside the collection plate 3, a temperature measuring plate 31 is installed. At the four corners of the insulating housing 11, shock-absorbing springs 14 are installed. On the insulating housing 11, a window 1 is provided. The window 1 is made of a transparent material.
[0037] On the insulating housing 11, a liquid injection port 111, an air inlet 112, and a liquid discharge port 113 are provided. The air inlet 112 and the liquid discharge port 113 are located on both sides of the liquid injection port 111. On one side of the transformer body 12, a storage tank 15 is installed. The storage tank 15 is installed on the insulating housing 11. The inlet of the storage tank 15 is connected to the liquid injection port 111 through a pipeline, and the outlet of the storage tank 15 is connected to the input pipe 23 through a pipeline. A coolant is provided inside the storage tank 15. A delivery pump (not shown in the figure) is connected in series to the input pipe 23. The delivery pump transports the coolant in the storage tank 15 into the input pipe 23, so that the coolant flows at a high speed in the input pipe 23. The storage tank 15 stores and buffers the coolant to avoid excessive impact of the coolant and affect the normal operation of the transformer body 12.
[0038] The input pipe 23, the intermediate pipe 22, the output pipe 21 and the vortex pipe 24 are all arranged on the insulating housing 11. The diameter of the intermediate pipe 22 is smaller than that of the input pipe 23 and the output pipe 21. An electromagnetic valve and a flow meter are installed in the output pipe 21. The electromagnetic valve and the flow meter in the output pipe 21 are electrically connected to the control system. The vortex pipe 24 is connected to the air inlet 112 through a pipeline. The vortex pipe 24 is distributed in a planar spiral. A plurality of filter plates 241 are rotatably arranged on the inner wall of the vortex pipe 24 in sequence through torsion springs. Filter meshes 242 are arranged on the plurality of filter plates 241. The diameters of the plurality of filter meshes 242 gradually decrease in sequence.
[0039] When the vortex pipe 24 performs dust removal work, air and dust are inhaled through one end of the vortex pipe 24. After passing through the vortex pipe 24 and the plurality of filter meshes 242 for dust removal, the air is discharged from the other end of the vortex pipe 24 and hits the coolant at high speed to form water mist, so as to quickly dissipate heat from the transformer body 12 through the water mist.
[0040] When the vortex pipe 24 is cleaned, the coolant is transported into the input pipe 23 through the coolant delivery system and the delivery pump. The control system simultaneously closes the electromagnetic valve in the output pipe 21. The coolant enters the storage tank 15 through the liquid injection port 111. The delivery pump works intermittently to extract the coolant in the storage tank 15 into the input pipe 23, so that the coolant enters the input pipe 23 intermittently, forming an impact of the coolant, so as to clean the filter mesh 242 through the intermittent coolant.
[0041] The intermittently moving coolant enters the vortex pipe 24 through the input pipe 23 and the intermediate pipe 22. Since a large amount of dust is deposited on the filter mesh 242, the resistance of the coolant passing through the filter mesh 242 is large. The coolant will push the filter plate 241 and the filter mesh 242 to flip by a certain angle. While the filter plate 241 flips, the torsion spring is compressed. The filter plate 241 flips by a certain angle and impacts on the vortex pipe 24. After that, the dust on the filter mesh 242 is washed away by the coolant and becomes less. The resistance of the coolant passing through the filter mesh 242 becomes smaller. At this time, the torsion spring is released, and the torsion spring pushes the filter plate 241 and the filter mesh 242 to flip reversely by a certain angle, and reversely pushes the filter plate 241 to impact on the vortex pipe 24 again. Through the intermittent movement of the coolant, multiple impacts of the filter plate 241 are realized, and the dust on the filter mesh 242 is impacted and dropped. After the coolant flushes the plurality of filter meshes 242 at the same time, the flushed coolant is discharged from the vortex pipe 24 into the air inlet 112 and discharged from the air inlet 112 of the voltage transformer, realizing the cleaning process of the plurality of filter meshes 242.
[0042] The cooling plate 2 and the collection plate 3 are both installed on the insulating housing 11. Multiple groups of cooling channels and multiple groups of collection channels are respectively arranged inside the cooling plate 2 and the collection plate 3. Multiple groups of spraying ports 202 and multiple groups of collection ports 203 are respectively arranged on the opposite sides of the cooling plate 2 and the collection plate 3. The multiple groups of spraying ports 202 and the collection ports 203 are facing the transformer body 12. One ends of the multiple groups of cooling channels are all connected to the output pipe 21, and the other ends of the multiple groups of cooling channels are respectively connected to the multiple groups of spraying ports 202. One ends of the multiple groups of collection channels are all connected to the multiple groups of collection ports 203, and the other ends of the multiple groups of collection channels are connected to the liquid discharge port 113 through pipes. The liquid injection port 111 and the liquid discharge port 113 are both connected to the coolant delivery system. Flow control valves and flow meters are installed in all the multiple groups of cooling channels, and the flow control valves and flow meters in the cooling channels are both electrically connected to the control system; Multiple groups of refrigeration plates 201 are provided, and the multiple groups of refrigeration plates 201 are sequentially arranged in the cooling channels; A collection cylinder 301 is arranged on the upper side of the collection plate 3, and the collection cylinder 301 is in close contact with the inner wall of the insulating housing 11. Multiple groups of temperature measuring plates 31 are provided, and the multiple groups of temperature measuring plates 31 are sequentially arranged in the multiple groups of collection channels; The multiple groups of spraying ports 202 and the multiple groups of collection ports 203 are facing each other. The control system adjusts the opening degree of the flow control valves in the multiple groups of cooling channels according to the temperature data detected by the multiple groups of temperature measuring plates 31.
[0043] Multiple groups of displacement sensors are arranged on the insulating housing 11. The displacement sensors are used to detect the displacement of the insulating housing 11. Spiral grooves are arranged at the four corners of the insulating housing 11. Lifting shafts 16 are threadedly connected in the spiral grooves. The lifting shafts 16 and the spiral grooves form a threaded seal. The upper ends of the lifting shafts 16 penetrate through the insulating housing 11 and are provided with handwheels 161. Scales are arranged on the handwheels 161. The lower ends of the lifting shafts 16 are connected to shock-absorbing springs 14. The shock-absorbing springs 14 are located in the spiral grooves. A contact plate 17 is rotatably arranged at the lower end of the shock-absorbing spring 14. A telescopic shaft (not shown in the figure) is connected between the contact plate 17 and the lifting shaft 16. The telescopic shaft is a telescopic structure, and the contact plate 17 is in contact with the ground.
[0044] The vibration damping effect of the voltage transformer is designed to be adjustable to face different usage scenarios. The staff rotates the handwheel 161 to the set scale. The handwheel 161 drives the lifting shaft 16 to rotate. The lifting shaft 16 drives the shock-absorbing spring 14 to rotate. While the shock-absorbing spring 14 rotates, it moves downward in the spiral groove. At this time, the number of turns of the shock-absorbing spring 14 between the bottom of the insulating housing 11 and the contact plate 17 becomes more, and the shock damping effect becomes stronger.
[0045] Connection plates and two kinds of semiconductors are arranged on both the temperature measuring plate 31 and the refrigeration plate 201. The connection plates are made of metal. The materials of the two kinds of semiconductors are different. One ends of the two kinds of semiconductors are both connected to the connection plates. The two kinds of semiconductors are electrically connected to the control system through wires; The connection plates and the two kinds of semiconductors on the temperature measuring plate 31 are the hot ends of the Seebeck effect, and the connection plates and the two kinds of semiconductors on the refrigeration plate 201 are the refrigeration ends of the Peltier effect.
[0046] Working principle: When the transformer body 12 is working, the control system controls the delivery pump to work, the solenoid valve in the output pipe 21 to open and the coolant delivery system to work. The coolant delivery system delivers the coolant to the storage tank 15 through the pipeline and the liquid injection port 111, and then the coolant in the storage tank 15 is extracted into the input pipe 23 by the delivery pump. The coolant flows in the input pipe 23, the intermediate pipe 22 and the output pipe 21 in turn. Since the diameter of the intermediate pipe 22 is smaller than that of the input pipe 23 and the output pipe 21, under the action of the Venturi effect, a negative pressure will be generated in the intermediate pipe 22, allowing the external air to pass through. The air inlet 112 enters the vortex tube 24, and the dust passes through the multiple groups of filters 242 in the vortex tube 24 in turn. The multiple groups of filters 242 filter the dust, and the vortex tube 24 is distributed in a planar thread. The dust and air continue to flow in the vortex tube 24. Since the dust and air have different inertia forces, the dust hits the inner wall of the vortex tube 24 and loses power. The dust is then deposited in the vortex tube 24, and the air passes through the vortex tube 24 in turn and is sucked into the intermediate tube 22. After being sucked through the intermediate tube 22, the air collides with the high-speed coolant to form aerosol, which is then transported from the output pipe 21 to the cooling channel.
[0047] When the aerosol coolant is delivered to the cooling channel through the output pipe 21, the flow meter in the output pipe 21 feeds back the flow data to the control system. The control system connects the two semiconductors on the multiple groups of refrigeration plates 201 to the circuit. The connecting plates and the two semiconductors on the multiple groups of refrigeration plates 201 are the cooling ends of the Peltier effect, while the heating end of the Peltier effect is not explained. The control system cools the aerosol coolant in the cooling channel through the cooling end to cool the aerosol coolant to a set temperature. The cooled aerosol coolant is sprayed onto the isolation cover 13 from the multiple groups of spray ports 202. The aerosol coolant increases the contact area with the isolation cover 13, thereby improving the cooling effect and allowing the transformer body 12 to dissipate heat quickly.
[0048] When the aerosol coolant is sprayed on the isolation cover 13, the control system connects the connecting plates and two semiconductors on the multiple sets of temperature measuring plates 31 to the circuit according to the data of the flow meter in the output pipe 21. The connecting plates and two semiconductors on the temperature measuring plates 31 are the hot ends of the Seebeck effect, while the cold ends are not explained. The coolant takes away the heat from the isolation cover 13, thereby reducing the temperature of the mutual inductor body 12. After heat exchange, the coolant is collected and converged downward by the collecting tube 301. The coolant after heat exchange enters the multiple sets of collecting flow channels and contacts the multiple sets of temperature measuring plates 31. At this time, the hot end temperature is higher than the cold end. The Seebeck effect generates current between the hot end and the cold end and transmits it to the control system. The control system detects the magnitude of the generated current and thereby obtains the temperature of the coolant after heat exchange in the multiple sets of collecting flow channels.
[0049] After the control system obtains the temperatures of the coolant in multiple sets of collection channels, it adjusts the opening degree of the flow control valve in the cooling channel according to the temperatures of the coolant in the multiple sets of collection channels; when the temperature in the collection channel is higher than the set temperature, the control system increases the opening degree of the flow control valve in the cooling channel directly above the collection channel, so that the coolant flow in the cooling channel directly above the collection channel becomes larger, so as to uniformly cool the isolation cover 13 and the transformer body 12, avoid the problem of local overheating of the isolation cover 13 and the transformer body 12, realize the targeted cooling of the isolation cover 13 and the transformer body 12, and improve the cooling effect; afterwards, the control system processes the current generated by the Seebeck effect through voltage transformation and rectification, etc., and uses it for the cooling of the refrigeration plate 201, so as to reduce the energy consumption of the voltage transformer while realizing the detection.
[0050] After the coolant passes through multiple sets of collection channels, it returns to the coolant delivery system through the drain port 113, and the coolant delivery system processes the coolant and reuses it.
